\qmlsignal QtQuick::TextEdit::linkActivated(string link)

\qmltype TextEdit
\instantiates QQuickTextEdit
\inqmlmodule QtQuick
\ingroup qtquick-visual
\ingroup qtquick-input
\inherits Item
\brief Displays multiple lines of editable formatted text.

The TextEdit item displays a block of editable, formatted text.

It can display both plain and rich text. For example:

\qml

TextEdit { width: 240 text: "<b>Hello</b> <i>World!</i>" font.family: "Helvetica" font.pointSize: 20 color: "blue" focus: true } \endqml

Setting \l {Item::focus}{focus} to true enables the TextEdit item to receive keyboard focus.

Note that the TextEdit does not implement scrolling, following the cursor, or other behaviors specific to a look and feel. For example, to add flickable scrolling that follows the cursor:

Flickable {
     id: flick
 
     width: 300; height: 200;
     contentWidth: edit.contentWidth
     contentHeight: edit.contentHeight
     clip: true
 
     function ensureVisible(r)
     {
         if (contentX >= r.x)
             contentX = r.x;
         else if (contentX+width <= r.x+r.width)
             contentX = r.x+r.width-width;
         if (contentY >= r.y)
             contentY = r.y;
         else if (contentY+height <= r.y+r.height)
             contentY = r.y+r.height-height;
     }
 
     TextEdit {
         id: edit
         width: flick.width
         focus: true
         wrapMode: TextEdit.Wrap
         onCursorRectangleChanged: flick.ensureVisible(cursorRectangle)
     }
 }

A particular look and feel might use smooth scrolling (eg. using SmoothedAnimation), might have a visible scrollbar, or a scrollbar that fades in to show location, etc.

Clipboard support is provided by the cut(), copy(), and paste() functions. Text can be selected by mouse in the usual way, unless \l selectByMouse is set to false; and by keyboard with the {Shift+arrow} key combinations, unless \l selectByKeyboard is set to false. To select text programmatically, you can set the \l selectionStart and \l selectionEnd properties, or use \l selectAll() or \l selectWord().

You can translate between cursor positions (characters from the start of the document) and pixel points using positionAt() and positionToRectangle().

This signal is emitted when the user clicks on a link embedded in the text. The link must be in rich text or HTML format and the link string provides access to the particular link.
